I have just bought efi Live and its connected to the car. Its a ws6 6 speed. Engine is bone stock. I have installed a Dana s60 rear with 4:11 gears. When I correct the parameter for the final drive gear my Speedo doesn't change. I am doing a full scan and full reflash. I would like to change and get into more but my reflash isn't changing anything. I am following the directions it gives me for saving the tune file first. I am following the countdown and it comes up and says that reflash was successful. I am lost.
